COUPLING FOR THE ENDS 0F ELASTIC OR OTHER EXERCISER-CORDS.

Specification of Letters Patent.

Patented Apr. 11, 1911.

Application filed. October 22, 1910. Serial No. 588,676.

To all whom it may concern:

Be it known that I, I-IARoLn JoriN Vann- HAM, a citizen of the UnitedKingdom of Great Britain and Ireland, and resident of 28 Gateley road,Brixton, London, England, have invented certain new and usefulImprovements in Couplings for the Ends of Elastic or otherExerciser-Cords, of which the following is a specification, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to spring hooks for cords, particularly the cordsof exercising apparatus, and to that form of hook which comprises atubularportion or socket adapted to receive the cord and from which acurved arm extends, the said arm forming the hook proper while a tongueattached to the socket and reaching to the end of the curved arm formsthe guard or hip.

The invention concerns this guard in particular, and as a secondaryfeature an improvement in the arm.

My guard comprises a spring placed within the said socket, one end ofwhich spring is bent to enter an aperture in the socket while the otherend reaches the end of the arm, said arm being preferably strengthenedby a rib and having a recess to receive the end of the spring.

In the drawings, Figure 1. shows a form of my invention. Fig. 2. shows ablank or stamping from which my hooks can be made. Fig. 3. shows asectional view of a hook made from a blank such as that shown in Fig. 2.

a is the elastic or other cord placed in the socket c of the hook andheld therein by metallic rings 5. The extended arm (1, which in thedrawings is shown integral with the socket, is bent over in hook fashionand has a strengthening rib (l pressed up in it.

e is the spring forming the guard, the end of which enters the slot-likeaperture f in the socket 0 being held therein by the pressure of thecord or rings.

The examples shown in Figs. 2 and 3 have lugs g and recesses h whichengage each other when the metal is bent round to form the socket. Theselugs and recesses are use ful to prevent lengthwise displacement of thecontacting edges of the socket if the same is made of light metal and issubjected to much strain.

The position and shape of the apertures f are unimportant providing theslot is suiticently low in the socket to bring the spring into contactwith the cord or rings. A recess on the inner side of the arm (Z and atits extremity serves to keep the guard from lat eral displacement.

It will be observed that my improved hook comprises two parts only.

WVhat I claim and desire to secure by Letters Patent is In a spring hookfor cords, the combination with a tapering shell or socket provided witha hook and with an opening, the latter being removed inwardly from thelarger end of the socket, of a spring guard for the hook, said guardhaving a portion disposed within the socket and provided with aprojection received withinv the aforesaid opening, a cord receivedwithin the socket, and a hard member encircling the cord which isadaptcd to bear against the spring guard within the socket and hold theprojection thereon in the opening aforesaid.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
